Nope..Id never dealt with verniers before and didnt have a clue how to
read them. Its not..obvious until you have been shown and then its a
palm to the forehead and Oh! Yes! Simple!

Wait until you find an old transit with 30 graduations on the
retrograde angular vernier. g Verniers were used for lots of things.
The ones one calipers and micrometers are pretty simple.


Didn't you ever wonder what all those other marks were for?

I never HANDLED one much. Had no need to do so. Why would I ?
Ive got tools out in the shop Ive never used before..and in some
cases..dont know what they are used for. When I find them...I usually
put them aside for investigation...but some of them Ive never found
out what they were for.

Hell...heres an example.....Ive got a handful of like items marked
Stanley. I put 2 of them into my pocket when I went to an antique tool
show and showed em around...and it was an hour before a guy looked at
em and lit up and told me what they were.

I gave him one for the ID and he was tickled ****less.

Good grief. How did you control the bores in your ark timbers before
you knew?
